TIE-PLATE.

- Application filed June 5, 1914.

' To all whom it may concern:

Be it known that I, Mon'rnrnn J. SILBER- uses, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tie-Plates, of which the following is a specification.

My invention relates to railway track construction and has particular reference to a novel tie plate and clip particularly adapted for use with screw spikes.-

It is common practice on many railroads to place beneath the rails on each tie a tie plate in order to increase the bearing surface between the rail and the plate. Such plates have taken many forms but few of those being adapted for use with screw spikes. In order to utilize this desirable form of fastening a special form of plate must be provided. Such a plate must pro vide for a secure and extended bearing for the head of the'screw spike, such bearing being preferably in the form of a plane surface whereby the flange or head of the spike may be rotated freely thereon.

In many of the screw spike tie plates provision is made for directcontact between the rail and the head of the spike. This re quires that the under surface of the spike shall be spherical or at least curved to correspond to the angle of the top surface of the rail base. Thus only a line or point con tact is secured between the spike and rail.

An object of my invention is to provide means whereby an extended bearing surface is secured, and also to provide means for utilizing a screw spike having a flange with a horizontal plane under surface. These results are secured by the use of a clip such as shown. lowever. due to inequalities and permissible variations, such a clip in order to certainly engage the rail base should have a limited line of contact with the tie plate, which contact line preferably acts a fulcrum. Thus a broad bearing secured between clip, rail base and spike, and the clip is certain to engage the rail under all conditions of variation in material.

In my former application, Serial No. 827,947. filed March 29, 1914.. issued as patent 1,100.848, dated June L3. 1914:, I have set forth a form of tie plate which possesses in a degree the characteristics thus far setforth. and the present invention relates to such further lmprovements 1n the art as conduce to even reater efiiciene Herein I 7 Serial No. 843,289.

provide for the interposition between the flanges of the tie plate and the edges of the rail base, of a portion of the clip which thus acts as a distance member bearing outwardly against the plate flange and inwardly against the rail, whereby the rail securely fixed against lateral horizontal dis understood, I have in the accompanying drawing and in the detailed description based thereon set forth a preferred embodiment of the invention. As, however, the particular embodiment is susceptible of modification without departing from the spirit and essence of the invention it is to be understood that the drawing and description are to be taken in an illustrative and not in an unnecessarily limiting sense.

. in the drawingl*igure 1 is a transverse section of a railway rail with which. an improved tie plate is associated; and Fig. 2 is aplan view of the same.

H aving particular reference to the drawings, the reference numeral 11 designates a. cross tie upon which rests the tie plate which comprises a body portion 12, and upstanding lateral flanges 13, 13, the space between the flanges 13 being suiliciently greater than the width of the base 14 of the rail 15 to provide a substantial side (clearance between the edges of the rail and the said tie flanges. The tie plate is provided with spike apertures at points substantially ialf way between its flanges and the edges of the rail with which it is designed to be associated.

Clips 16, 16 ar employed for holding the rail in position relative to the plate, said clips each including a body portion 1'? and laterally ext iding wing portions 18 and 19. The body portion is adapted to fit snugly within the clearance space between the tie plate flange 13 and the edge of the rail and in order to provide for slight inaccuracies found in practice the said body portion 17 may advantageously be made with a slight downward taper so as to exert e. lateral wedging action as it is forced to its position by means of the screw spike disposed within a central aperture of the clip and the aperture of the plate. The wing 18 of the clip bears upon the tie plate flange 13 as a fulcrum and by means of the spike the wing 19 of the clip is clam ed firmly upon the upper face of the rail base, the lower face of the wing 19 being preferably inclined to fit the upper inclined face of the rail base. Thus it will be seen that the action of the screw spike upon the clip 16 acts to clamp the rail both horizontally and vertically in place within the rail clip which latter is the tie plate and clip, the clip having shoulders abutting one against a shoulder of the plate and the other directly against the rail base, while the upper face of the clip is plane to present a perfect bearing for the fiat head of the screw spike.

I claim:

1. In a rail fastening device, the combination with a tie plate provided with opposite upstanding edge flanges, the inner edge faces of said flanges being perpendicular to the plane of the tie plate and the upper faces of said flanges being disposed at right angles to said edge faces, of rail engaging clips having downwardly tapering body portions and oppositely-disposed laterallV-eXtending Wing portions engaging respectively the tie plate flange and the rail base flange, the under face of said rail. engaging wing portion being beveled to conform to the slope of the rail base flange and the tie plate flange engaging wing portion having its under face conforming to the upper face of the tie plate flange.

2. A combination tie plate and clip comprising a rail-supporting plate having a pair of oppositely facing flanges arranged to receive a rail base therebetween With side clearance, and a clip having a wedge-shaped body portion with laterally projecting wings, the body arranged to snugly fit with in the clearance space between the plate flange and rail base and the wings to overlie the said rail base and plateflange respectively, the said plate and clip provided with means for holding the same in associated relation with a rail and with a suitable support, substantially as described.

3. A combination tie plate and clip comprising an apertured plate having a pair of oppositely facing flanges arranged to receive a rail base therebetween with side clearance, and an apertured clip having a Wedgeshaped body portion with laterally projecting wings, the body adapted to snugly fit within the clearance space between the plate flange and rail base and the wings to over-
